I wonder if anyone on the forum here has optimized alignment (geo) for the track?
Lotus has slightly different 'track' settings compared to the normal 'road' setup.
Some of the guys who race Elise's in the UK usually advise a setting like this for track use on standard or uprated suspension:
Front:
Camber -1°
Toe OUT 0°15"
Rear:
Camber -2°
Toe IN from 0°30" to 1°00"
Lotus also has some 'track' settings they use for the LSS and they are similar to this.
-1° camber at the front is about the max you can run on the S2 without modifying (shaving) the hub carrier or mounting plinth on the wishbone.
The toe settings can be reduced (to close to '0') if you change the standard rubber bushes in the wishbones to nylon/nylatron or even rod ends as these will reduce (or almost eliminate) the front-back movement in the wishbones and reduces/stop the toe changes under cornering and brake/acceleration forces.
Take care when reducing rear toe though as you don't want the rear to go to toe OUT under load. This is what early (1991/2) MR2's were infamous for.
The Elise always runs toe OUT at the front to make the turn-in more positive and control the way the car corners better.
